Requisites:  Before taking this unit you must take MA20216 and take MA20218 and take MA20219 and take MA20220 and take MA30041. Students may also find it useful to take MA20221 before taking this unit. 
Description:  Aims: To provide an accessible but rigorous treatment of initialvalue problems for nonlinear systems of ordinary differential equations, including existence and uniqueness problems, maximally defined solutions and Lyapunov stability theory. Foundations will be laid for advanced studies in dynamical systems and control. The material is also useful in mathematical biology and numerical analysis. Learning Outcomes: After taking this unit, students should be able to: * Demonstrate understanding of existence theory for the initialvalue problem, Lipschitz conditions and uniqueness, maximal intervals of existence, local and global flows, limit sets, basic Lyapunov stability theory including LaSalle's invariance principle, asymptotic stability and linearization about equilibria. * State and prove basic results in the theory of ordinary differential equations including existence and uniqueness of solutions, properties of limit sets, Lyapunov's stability theorem and LaSalle's invariance principle. * Analyse the stability properties of equilibria in the context of simple examples. Skills: Numeracy T/F A Problem Solving T/F A Written and Spoken Communication F (solutions to exercise sheets, problem classes) Content: Motivating examples from diverse areas. Existence of solutions for the initialvalue problem. Maximal intervals of existence. Local Lipschitz conditions and uniqueness of solutions. Local and global flows (dynamical systems). Limit sets and their properties. Stability and asymptotic stability, Lyapunov functions and LaSalle's invariance principle. Linearization about equilibria and asymptotic stability.
